There is a good potential to increase the brand awareness by using such pen drives. They come in sizes ranging from 4gb to 32gb and are very easy to handle. The different design of this pen drive makes it more secure to keep with you, even in wallets, unlike the traditional designs. Even from the creativity point of view, it is good to have this one.
